Jon Hamm will never be without underwear again, thanks to Jockey! Whether or not he'll actually wear it, however, remains unknown.

The New York Daily News recently reported that Hamm, 42, was asked by show producers to wear underwear while sporting tight suits on the set of AMC's Emmy-winning series Mad Men. A source explained to the Daily News, "This season takes place in the 1960s, where the pants are very tight and leave little to the imagination. Jon's impressive anatomy is so distracting that they politely insisted on underwear."

"Most of it's tongue-in-cheek, but it is a little rude," the actor, who has been dating Jennifer Westfeldt since 1997, tells the new issue of Rolling Stone. "It just speaks to a broader freedom that people feel like they have -- a prurience . . . They're called 'privates' for a reason, I'm wearing pants, for f--k's sake. Lay off."

"But whatever," he added. "I guess it's better than being called out for the opposite."
